[PATCH] gpio: pinctrl: Initialize Armada-XP GPIO/Pinctrl drivers at arch_initcall

[Joshua Scott <joshua.scott@xxxxxxxxxxxxxxxxxxx>]

The Armada-XP contains a set of GPIO pins. These pins may be used to take
other hardware out of reset. However, the drivers used are currently not
initialized until quite late in the boot process (module_platform_driver).

This patch replaces the use of module_platform_driver with arch_initcall
in the two drivers that are used to control the GPIO pins. This allows for
drivers using subsys_initcall or later to access to the pins.
